熋!
Almost instantly, everyone felt the temperature even from such a distance.
Furthermore, the raging fire raged along the suspension bridge and directly stained the trouser legs of the security personnel, immediately emitting a crackling sound.
"Hurry up and save him!"
Witnessing this scene with his own eyes, He Hongbo immediately panicked.
Immediately after, another security guard took off his shirt and covered his companion's trousers without saying anything. It took him a lot of effort to put out the fire.
Immediately after, everyone turned around and saw a scene that they would never forget for the rest of their lives.
The fire on the suspension bridge was still burning, and it only gradually extinguished after dozens of seconds.
Silence!
At this moment, the surroundings were eerily quiet.
No one had expected things to turn around so quickly.
For a moment, the netizens in the live broadcast room saw it the clearest. Through the live broadcast, they could even clearly see how the blazing flames appeared.
The strong visual impact made them all scared silly.
"What the hell is going on?”
"I'm f * cking dumbfounded!"
"Didn't you say that the Phosphorescence Fire is a cold flame? How did it become a raging fire in the blink of an eye?”
"If you get burned, you can directly burn someone into charcoal!”
"What happened? What was that updraft just now?!”
At this moment, the netizens in the live broadcast room were all pale with fear. After all, no matter who saw that terrifying scene, they would probably have the same reaction.
This so-called suspension bridge was too terrifying!
However, the most inconceivable thing was, how did the fire form?
Wasn't it said that the Phosphorescence Fire was a cold flame of zero degrees?
At this moment, Professor He Hongbo and the others stood rooted to the ground with ugly expressions on their faces. They felt a layer of white sweat on their backs.
Especially the security guards on the bridge.
If Zhang Yingxue had not reminded him in time, he might have been burnt to a crisp by now.
He swallowed his saliva with lingering fear.
At this moment, he suddenly noticed the torch in his companion's hand.
"Quickly destroy it!"
Although he didn't know how the fire was formed, he was terrified when he thought of the situation just now.
After the torches were extinguished, everyone fell into another suspicion.
What was going on?
How did the originally harmless phosphorous fire turn into a raging fire that could burn everything in an instant?
"It's marsh gas!"
At this moment, Zhang Yingxue suddenly spoke.
What was that?
Hearing her words, everyone hurriedly looked over.
At this moment, Zhang Yingxue recalled with lingering fear," That's right. When I was young, my brother told me that phosphorous fire is indeed a cold flame of zero degrees Celsius, but under certain conditions, it can quickly turn into a high-temperature fire and even cause an explosion!”
"For example, when I was young, my brother and I passed by a farm. The eggshells piled up outside formed harmless phosphorous fire, and the corpses of the farmed animals piled up for too long to form a large amount of marsh gas!”
"Once the marsh gas and the phosphorous fire are released together, they can form a raging fire!”
What was that?
There was such a thing?
At this moment, everyone's expression was solemn.
"That's right!" At this time, Yang Shurou nodded and said,""When he came up just now, I smelled an ascending airflow from the mountain stream below.”
"If I'm not wrong, that smell is definitely the smell of marsh gas!”
That's right.
Yang Shurou had felt that there was something fishy about the suspension bridge. Now, she was confident that there was a large amount of marsh gas stored under the mountain stream.
Hearing this, everyone was enlightened.
However, what exactly was going on?
Where did the marsh gas come from?
At the same time, the netizens in the live broadcast room did not understand what was happening.
"What do you mean?"
"Biogas, what's the use of marsh gas?”
"There are a lot of tricks up there. If you can't grasp them, let me grasp them! The so-called marsh gas was a highly concentrated flammable gas. There were many news reports of children throwing firecrackers into the sewers and getting blown up because there was too much marsh gas in the sewers!”
"That's right. Although the phosphorous fire is a cold flame, once it comes into contact with the marsh gas, it will form an extremely high temperature fire!”
"This is a chemical reaction. This kind of fire can even produce a strong explosion!”
Gulp!
After seeing the Almighty's explanation in the live broadcast room, the other netizens couldn't help but gulp.
It was only then that they realized that the suspension bridge was just a bait, and the real fatal trap was the marsh gas stored under the mountain stream.
Phosphorescence was not harmful to people, and it would confuse people who entered the tomb, making them think that the so-called white phosphorous was only used to prevent the suspension bridge from rotting.
Little did he know that this was the second part of the fatal trap!
When the wildfire was lit, the people who entered the tomb would think that it was just an anti-corrosion measure, so they would walk on the suspension bridge.
However, once the marsh gas from below surged up, it would form a violent explosion and flame when it came into contact with the phosphorous fire. If the security personnel had been a step slower, they would have been burned to ashes by now.
But the question now was, where did the marsh gas come from?
The two security guards couldn't help but look at the professionals.
"So it's like this…"
At this moment, Professor He Hongbo suddenly nodded with a serious face.
He finally understood now. No wonder Zhang Yingxue kept saying that something was wrong.
Thinking of the key point, he looked at the bottomless mountain stream below and guessed with a solemn expression,"Looks like the real danger is down there. What a terrifying method. This mechanism even uses psychology.”
"If I'm not wrong, there might be a pit of ten thousand people down there!”
What was that?
Mass grave?
Hearing his words, the two security guards widened their eyes.
Although they had all undergone professional training, they had never seen such a scene before.
However, He Hongbo nodded.
Although he couldn't see the situation below, he dared to pat his chest and guarantee that there were definitely piles of bones below!
With so many skeletons piled up together, after years of decay, the marsh gas formed had been deposited below, so the mountain stream below had been directly turned into a large marsh gas tank.
However, this situation was still difficult for everyone present to accept, except for Yang Shurou.
But thinking about it carefully, this possibility did exist during the Qin Dynasty.
"During the Qin Dynasty, so many people died!”
Thinking of this, Professor Wang couldn't help but swallow his saliva and say,"If I am not wrong, the ten thousand people pit under this mountain stream is the place that provides the air…"
"After years of decay and settling, it turned into a marsh gas tank. When the updraft lifted the marsh gas, it would have a chemical reaction with the phosphorous fire!”
At this moment, the netizens in the live broadcast room were all stunned.
Originally, they were already shocked enough when they saw the sudden change in the Phosphorescence. Now that they heard that there was actually a mass grave below, how could the netizens still calm down?
"Are you kidding me?"
"Mass grave? How many people were buried here?”
"Nothing is impossible! Qin Shi Huang was the first emperor in history, but he had killed many people on the way to Qin's unification.”
"That's right! Just Baiqi alone had killed 400,000 surrendered soldiers! Moreover, Bai Qi was buried here, so it made sense that there was a ten thousand man pit here!”
"Where do you think the slaves sent to build the Great Wall are after they die?”
